Banksia robur, commonly known as swamp banksia or, less commonly, broad-leaved banksia grows in sand or peaty sand in coastal areas from Cooktown in north Queensland to the Illawarra region on the New South Wales south coast. It is often found in areas which are seasonally inundated. Although it was one of the original banksias collected by Joseph Banks around Botany Bay in 1770, it was not named until 1800 by Cavanilles, with a type collection by Luis Née in 1793.
